Note that cupshelpers is in /gnu/store/n5ml8i1k1g5d79damckfv24kzx4z6gn5-system-config-printer- 1.5.15/lib/python3.9/site-packages, which does not get correctly added to GUIX_PYTHONPATH in the wrapper. On a separate note, version 1.5.16 has been released and should be considered for upgrading. Cheers
